[Problem that the invention seeks to solve]

A conventional terminal emulator device directly transmits input from a keyboard device 7 to a host computer 1, and also directly transmits data sent from the host computer 1 to a display device 6.
Since the data is to be output to the display device 6, it is not possible to process the data to be sent in advance on the terminal device side or to process the received data before outputting it to the display device 6. When transferring files using , the file transfer utility software IO is required on the host computer 1 side to transfer files, so there are some problems such as file transfers can only be performed with a specific host computer 1. There was a problem.

This invention was made to solve the above-mentioned problems, and it is possible to provide data processing capability on the terminal device side, and also eliminates the need for file transfer utility software on the host computer side. The purpose is to obtain a terminal emulator device that can be connected to a host computer.

[Means for solving problems]

A terminal emulator device according to the present invention is a means for separating input data from a keyboard device of a terminal device into data that is sent directly to a host computer, data that is sent after being processed, and data that is used to control the terminal device itself. , and means for separating data received from the host computer into data that is output directly to the display device of the terminal device and data that is output to a file.

[Effect]

The terminal emulator device according to the present invention has a certain degree of information processing ability as described above, and can not only directly send input data from the keyboard device to the host computer, but also capture one line of input data and its contents. from,
Some are converted into TSS command strings of the host computer and sent to the host computer, others are used to change the output light of received data (display device or file on the terminal device), define commands, etc. It generates commands to control itself and outputs data received from the host computer to a file on the terminal device, eliminating the need for file transfer utility software from the host computer. made possible.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 to 9 and 12 are equivalent to those given the same reference numerals in FIG. 4, 13 is keyboard input transmission and command execution software, and 14 is data reception software. The host computer 1 internally has various TSS commands 9 as part of the O8, but does not have file transfer utility software. Further, the terminal device 2 has the keyboard input transmission and command execution software 13 and data reception software 14 therein.

Next, the operation of this invention will be explained. First, the flow of control over the manual keystrokes from the keyboard device 7 will be explained. The manual input of the keys on the keyboard device 7 is
Keyboard input transmission and command execution software 13
is taken into the terminal device 2 and processed. Second
The figure shows a flowchart of the keyboard input transmission and command execution software 13. Input to the keyboard device 7 is taken in by subroutine 5BR1.

At this time, if the input data is a special character set in advance, step STI determines that mode switching is to be performed, and mode switching subroutine 5BR3 selects direct transmission mode, data conversion transmission mode, terminal The mode is switched to one of the device control modes. If the input from the keyboard device 7 is not a special character, the process proceeds to the next step and branches according to the current mode in step ST2. If the current mode is direct transmission mode, after one character is transmitted by subroutine 5BR3, input one character from the keyboard again by subroutine S.
Return to BRl. If the current mode is the data conversion transmission mode, the one-line input subroutine 5BR4 from the keyboard device 7 stores the input from the keyboard device 7 in the key cover sofa until a carriage return (hereinafter referred to as CR) is input. do. After the CR is entered,
Conversion subroutine 5 using macro command conversion table
With BR5, the contents of the keeper sofa are stored in the host computer 1.
After being converted into a TSS command string and transmitted in the data transmission subroutine 5BR3, the process returns to the one character input subroutine 5BR1 from the keyboard. In this way, when a macro command conversion table is used for conversion to a TSS command string, a terminal emulator device that can execute a desired operation with a certain command on any host computer can
This can be achieved without changing the hardware, just by changing the macro command conversion table. If the current mode is the terminal device control mode, after executing the one-line input subroutine 5BR4 from the keyboard, the command execution subroutine 5BR
Control is transferred to 6.

This command execution subroutine 5BR6 executes commands specified by the contents of the keypad, such as terminating the terminal emulator software and changing the destination of received data (display/file).

The macro command conversion table is updated and the data file received from the host computer 1 is displayed. In this command execution subroutine 5BR6, after completing the execution of commands other than terminating the terminal emulator software, the process returns to the one character input subroutine 5BR1 from the keyboard.

Next, processing of data received from the host computer 1 will be explained. Data transmitted from the host computer 1 in FIG. 1 is transmitted to the R5232C interface 5 through the serial controller 3°R3232C cable 4. When the R5232C interface 5 receives data, it issues an interrupt to the terminal device 2. The terminal device 2 has data receiving software 14 as an interrupt processing routine, which takes in one character from the R5232C interface 5 and outputs it to the display device 6 or a file on the secondary storage device 8. FIG. 3 shows a flowchart of this data receiving software 14. R523
When an interrupt is received from the 2C interface 5, the data receiving software 14 starts execution and the R5232C
Data is received from the interface 5 by a one character data reception subroutine 5BR7.

Next, in step ST3, in the terminal device control mode of the keyboard input transmission and command execution software 13, the data output destination specified in the command execution subroutine 5BR6 is determined. If the data output light is the display device 6, subroutine 5BR8
Outputs one character to the display device 6 and leaves the interrupt processing program. If the output light of the data is not the display device 6, the subroutine 5BR9 outputs one character to the designated file in the secondary storage device 8, and then exits from the interrupt processing program.

Next, a case will be described in which a file is transferred between the file 12 of the host computer 1 and the secondary storage device 8 of the terminal device 2 using the terminal emulator device of the present invention. First, in the terminal device control mode of the keyboard input transmission and command execution software 13, the command execution subroutine 5
Specify a file as the destination of the received data on the BR6, and then input a macro command on the host computer l to output the file contents to the terminal in data conversion transmission mode.

This macro command has a function that deletes unnecessary output from the file, and uses this to transfer the file. Therefore, in this file transfer between the host computer 1 and the terminal device 2, the host computer 1 does not need to be equipped with utility software for file transfer.

In addition, although the above embodiment has been explained using the terminal device 2 having the secondary storage device 8, as the storage destination of the received data,
The main memory of the terminal device 2 may be used instead of the secondary storage device 80.

In addition, if O3 is installed in a terminal device, it becomes possible to realize the function of a terminal emulator as one command of O8, and furthermore, the command execution subroutine 5 of the keyboard input transmission and command execution software 13
It is also possible to execute the O3 command on BR6.

〔Effect of the invention〕

As described above, according to the present invention, input from the keyboard device is not only sent directly to the host computer, but also the keyboard input is captured line by line and a TSS command string on the host computer is generated from the contents. Since the configuration is configured to generate commands for sending and controlling the terminal device itself, the output light of received data can be output not only to the display device but also to a file on the terminal device. This eliminates the need for special file transfer utility software on the host computer side for file transfer, and has the effect of providing a terminal emulator that can transfer files with any host computer.
